FIELD OF INVENTION

The invention relates to a method, a communication system, and acommunication device for transmitting data within a communicationnetwork.

BACKGROUND OF THE INVENTION

In known voice communication systems, when a connection is being set upfrom a calling communication facility to a called communicationfacility, a call number of the calling communication facility is oftensignaled and can be displayed on a display unit of the calledcommunication facility. Voice communication systems of this type are forexample ISDN-based exchanges (ISDN: Integrated Services Digital Network)and ISDN telephones, which can be linked by way of these, it beingpossible for the exchanges to be arranged in the public telephonenetwork or private communication networks belonging to companies ororganizations. The transmission and display of incoming call numbers isalso standard for mobile radio communication.

Modem communication facilities also frequency allow, in addition to thedisplay on the display unit, terminal-specific storage of transmittedcall numbers and further connection data for incoming connections incall logs. Lists of caller call numbers of incoming accepted and/or notaccepted calls are frequently stored in such call logs.

When call logs are used, it is generally possible with knowncommunication facilities to use the connection data stored in the calllogs to initiate the setting up of a further connection from the calledcommunication facility to the originally calling communication facility.Such setting up of a further connection is generally initiated manuallyby the called subscriber, by selecting an entry from a call log on thedisplay and by way of an input means on the originally calledcommunication facility, and initiating the setting up of the furtherconnection for this. It is thus possible for a subscriber for example,who identifies that he/she has been called in his/her absence, to callthe original caller back in a simple manner.

A further known communication service is an email communication, whereina subscriber—using an email address for addressing purposes—can transmita text-based message to a further subscriber. An email address astransmission destination can hereby be taken for example from a previousemail traffic, in which the further subscriber took part.

SUMMARY OF INVENTION

The object of the present invention is to specify a method and acommunication terminal for the more flexible use of differentcommunication services. A further object is to specify a communicationsystem for implementing the method.

This object is achieved by a method, a communication system and acommunication facility as claimed in the claims.

Advantageous embodiments and developments of the invention are set outin the dependent claims.

With the inventive method for transmitting data to a first subscriber afirst primary service communication facility for communication by way ofa primary communication service and a first secondary communicationfacility for communication by way of a secondary communication service,which in particular is different from the primary communication service,are assigned to the first subscriber. In the inventive method primaryaddress information is assigned to the first primary servicecommunication facility and secondary address information is assigned tothe first secondary service communication facility, whereby, in thecontext of a connection signaling from the first primary servicecommunication facility to a second primary service communicationfacility, the primary address information and the secondary addressinformation is transmitted to the second primary service communicationfacility by means of the primary communication service and the secondprimary service communication facility identifies the transmittedprimary and secondary address information and stores it in an addressbook with mutual assignment. For the transmission of data to the firstsubscriber the stored secondary address information is transferred fromthe second primary service communication facility to a second secondaryservice communication facility. The data to be transmitted is alsotransmitted by way of the secondary communication service to the firstsecondary service communication facility using the transferred secondaryaddress information.

It is a particular advantage of the invention that the secondary addressinformation is transmitted by way of the primary communication serviceand is thus available at the second primary service communicationfacility and/or the second secondary service communication facility,without a complex and possibly error prone manual or electronicdetermination—for example by way of a database or communicationdirectory—being required at the second primary service communicationfacility and/or the second secondary service communication facility. Italso proves to be advantageous that the transmission of data to thefirst subscriber is permitted by way of the second communication serviceusing the secondary address information, it being possible for thesecond communication service to be different from the firstcommunication service and/or the secondary address information to bedifferent from the primary address information.

In one advantageous embodiment of the invention the primarycommunication service can be provided for bidirectional voice, videoand/or multimedia communication—preferably based on a line-switched orpacket-oriented real-time protocol. Additionally or alternatively thesecondary communication service can be provided for unidirectionalmessage transmission by means of text, voice, video and/or multimediadata—in particular based on a protocol for non-real-time communicationor based on a protocol for real-time communication with lower real-timerequirements. The secondary communication service is preferably email,in particular according to SMTP (Simple Mail Transfer Protocol) or textmessaging using a push method, in particular instant messaging, whereintext messages are transmitted for immediate display at a receiverterminal.

In a further advantageous embodiment of the invention the primaryaddress information can also be represented by a call number, an IPaddress (IP: Internet Protocol), an E.164 number according to ITU-Trecommendation (ITU-T: Telecommunication Standardization Sector of theInternational Telecommunication Union), a URI (Uniform ResourceIdentifier) of a voice over IP service or an ENUM (ENUM: telephonenumber mapping) identifier of a voice over IP service. The secondaryaddress information can be represented by an email address or an instantmessaging identity. In particular the secondary address information canbe address information, which is meaningless in a previous primarycommunication service and is generally not transmitted.

In an advantageous development of the invention the transfer of thestored secondary address information from the second primary servicecommunication facility to the second secondary service communicationfacility and/or the transmission of the data to the first secondaryservice communication facility can be initiated by the detection of aselection of an entry in the address book by the second primary servicecommunication facility or the second secondary service communicationfacility.

In a further advantageous development of the invention the address bookcan be configured as a connection schedule, a call log and/or an emailaddress book, with which incoming and outgoing connections canrespectively be stored at a communication facility with assignment to acall number of the communication partner. The call log or connectionschedule can hereby be limited to connections, which correspond to aspecific criterion. This criterion can be for example an adopted stateof the connection—e.g. accepted, rejected—the communicationdirection—e.g. incoming, outgoing—and/or time information—e.g. forlisting separately by calendar days. The entries in the address bookhere can be stored permanently or just temporarily and can be deletedafter specified or unspecified time intervals. The address book can alsobe configured as an email address book or contact list, in which forexample an assignment can be made between email addresses and callnumbers. Also the address book can be provided in particular by thesecond primary or second secondary service communication facility or bya server facility.

BRIEF DESCRIPTION OF THE DRAWINGS

An exemplary embodiment of the invention is described in more detailbelow with reference to the schematic diagrams in a drawing, in which:

FIG. 1 shows a communication system with two terminals, which are linkedby way of a telephone network for voice communication and two furtherterminals, which are linked by way of a data network for emailcommunication, and

FIG. 2 shows a communication system with two terminals respectivelycomprising a primary and secondary service communication facility, saidterminals being linked by way of a data network.

DETAILED DESCRIPTION OF INVENTION

FIGS. 1 and 2 respectively show schematic diagrams of a communicationsystem for implementing the inventive method for transmitting data to afirst subscriber. In FIG. 1 the first subscriber is assigned a firsttelephone EG1 as a first primary service communication facility and afirst email client EM1 as a first secondary service communicationfacility. The first telephone EG1 can hereby be linked by way of thetelephone network PSTN by way of a primary communication service tofurther telephones—in particular to a second telephone EG2 as a secondprimary service communication facility. This second telephone EG2 isassigned to a second subscriber, to whom a second email client EM2 isalso assigned as a second secondary service communication facility. InFIG. 1 the said terminals EG1, EM1, EG2, and EM2 are shown asrectangles.

The second subscriber can use the second email client EM2 to set up anemail communication in the context of a secondary communication serviceto the first email client EM1 of the first subscriber by way of a datanetwork IPNW. The link between the two email clients EM1 and EM2 is inparticular packet-oriented, preferably using the IP-based SMTP protocol,and is shown as the dot-dash line SMTPV in FIG. 1 for clarity. The linkbetween the first telephone EG1 and the first telephone EG2 isline-oriented in the present exemplary embodiment and is shown by acontinuous line TV.

Further components of this exemplary embodiment are a first exchangePBX1 using line-oriented methods to control and administer the firsttelephone EG1, a first database PBXDB1, which is linked to the firstexchange PBX1, a second exchange PBX2 to be linked to the secondtelephone EG2 and a second database PBXDB2, which is linked to thesecond exchange PBX2. It should be assumed that the exchanges PBX1, PBX2and telephones EG1, EG2 communicate with one another by means of an ISDNprotocol or an ISDN-based protocol. FIG. 1 shows the exchanges PBX1,PBX2 as rectangles, with the databases PBXDB1, PBXDB2 stylized ascylinders. The link between the first exchange PBX1 and the firsttelephone EG1 is designated as PBXK1 and between the first exchange PBX1and the first database PBXDB1 as DBK1, being shown as continuous lines.A similar representation and designations PBXK2 and DBK2 are usedbetween the second telephone EG2 and the second exchange PBX2, as wellas on to the second database PBXDB2.

An address transfer unit AE, a receive unit REC, an identification unitEE and a storage control unit SE as components of the second telephoneEG2 are also shown schematically as rectangles within the secondtelephone EG2. The receive unit REC linked to a communication input ofthe second telephone EG2 hereby in particular carries out the task ofreceiving incoming connection signaling—for example from the firsttelephone EG1—with address information transmitted in the context of theconnection signaling. The identification unit EE linked to the receiveunit REC and the storage control unit SE identifies the addressinformation received by the receive unit REC as primary and secondaryaddress information and transfers it for storage in an address book ofthe storage control unit SE. The storage control unit SE stores theidentified primary and secondary address information in the address bookwith mutual assignment. The address book is configured in FIG. 1 as acall log CALLLOG provided in the second database PBXDB2, in which allincoming calls are stored. Communication between the storage controlunit SE and the second database PBXDB2 takes place in the presentexemplary embodiment by way of a control input of the second telephoneEG2 by way of the link PBXK2 to the second exchange PBX2 and on by wayof the link BDK2 to the second database PBXBD2, it being possible forthe control input to be identical to the communication input inalternative embodiments.

If the arrangement of the communication facilities—as shown in FIG. 1—isstructured so that the first telephone EG1 and the first email clientEM1 are assigned to a source communication system and the secondtelephone EG2 and the second email client EM2 are assigned to adestination communication system, then the address book is characterizedin that it is arranged in the destination communication system, whilethe first database PBXDB1 is associated with the source communicationsystem.

The address transfer unit AE, like the storage control unit SE, also hasa link to the control input of the second telephone EG2. The addresstransfer unit AE uses this to read out an entry stored in the call logCALLLOG—in particular the secondary address information of the entry—andto transfer it by way of a link to the second email client EM2.

The link between the second telephone EG2 and the second email clientEM2 is shown with a broken line by a CTI link CTIK, where CTI stands forComputer Telephony Integration and means for controlling and/orinterrogating the second telephone EG2 are provided by a computerapplication, like the second email client EM2, or by a furthercommunication facility. The underlying CTI communication protocolprovided can be for example the CSTA protocol (CSTA: Computer SupportedTelephony Application). An optional link between the first telephone EG1and the first email client EM1 is not significant in the context of theexemplary embodiment and is therefore not shown.

A communication and/or messages in the context of the inventive methodare shown in FIG. 1 by single or double arrows. In the exemplaryembodiment an assignment table ZUORD, stored in the first databasePBXDB1, is also provided for an assignment of call numbers and emailaddresses of terminals, which are administered by the first exchangePBX1. The assignment table ZUORD is shown in the drawing as a two-columntable with the headings RUNO for stored call numbers and EMAIL forstored email addresses. In FIG. 1 the assignment table contains onevalue pair RUNO1 and EMAIL1, and further value pairs for furthersubscribers or terminals shown by dots.

FIG. 1 also shows the caller log CALLLOG as a multi-column table. Thedata for incoming communication stored therein in particular includesthe arrival time of the incoming communication (shown as DATE), the callnumber of the caller of the incoming communication (shown as RUNO), anassociated email address (shown as EMAIL) of the subscriber and atransmitted display name of the caller (shown as NAME). The caller logCALLLOG is empty as a possible initial state. The values of the callerlog CALLLOG shown in FIG. 1 are values which are only input during thecourse of the method.

The call numbers shown in the figures as primary address information andthe email addresses shown as secondary address information designateaddresses for identifying communication facilities and are used to finda destination, for routing purposes and to direct data in a respectivecommunication service. It should be noted in particular here that theemail addresses have no significance with respect to addressing in theprimary telephony communication service. The email addresses areexternal addresses of the primary communication service and are not usedin this and according to the invention are transmitted withoutmodification by components in the signaling path to the receivingcommunication facility—in this instance the second telephone EG2.

The initial situation in FIG. 1 is a rest state for all thecommunication facilities EG1, EG2, EM1, EM2 mentioned above. On thisbasis the first subscriber initiates an attempted connection to thesecond telephone EG2 at the first telephone EG1. In the context of thisattempted connection the first exchange PBX1 or the first telephone EG1determines an associated email address EMAIL1—as secondary addressinformation—of the first subscriber for a call number RUNO1—as theprimary address information—of the first telephone EG1, by interrogatingthe assignment table ZUORD in the first database PBXDB1. Such assignmentpairs are configured and/or administered in the assignment table ZUORD.If there is an entry in the assignment table ZUORD for the call numberRUNO1—as indicated in the present exemplary embodiment by the value pairRUNO1-EMAIL1 shown in the assignment table in FIG. 1—the email addressEMAIL1 associated with the call number RUNO1 and determined istransmitted to the first exchange PBX1 and/or to the first telephone EG1by means of the message ABFR.

A connection signaling for the first telephone EG1 is then initiatedfrom the first telephone EG1 or from the first exchange PBX1 to thesecond telephone EG2 by way of the connection TV. A call number RUNO2assigned to the second telephone EG2 is used for addressing and/ornetwork path control for the connection signaling. Connection signalingis referred to hereafter as CALL, being shown in the figure as an arrowpointing toward the second telephone EG2. The destination address—inthis instance the call number RUNO2 of the second telephone EG2—is addedas a subscript with address information transmitted in the connectionsignaling and of relevance in the context of the invention being givenin parentheses as a parameter. According to the invention the firsttelephone EG1 also transmits the determined associated email addressEMAIL1 of the first subscriber in addition to the call number RUNO1 ofthe first telephone EG1. The email address EMAIL1 is transmitted fromthe first telephone EG1 to the second telephone EG2 in particular withconnection setup signaling from the first telephone EG1 or a subsequentsignaling initiated by an inquiry message of the second telephone EG2.Transmission here takes place as a function of the underlyingtransmission system, for example in the D-channel or a subscriber tosubscriber segment (so-called user to user signaling) of an ISDNconnection or in a protocol element of a packet-oriented telephoneconnection by means of SIP (Session Initiation Protocol) of the IETFworking group (IETF: Internet Engineering Task Force) or by means of theITU-T recommendation H.323. Protocol elements already provided for thepurpose can be used to transmit the call number RUNO1, these beingtransmitted to the called terminal anyway for example with a signalingby means of CLIP (Calling Line Identification Presentation).

Further to the incoming signaling the received second telephone EG2and/or the second exchange PBX2 detects the data transmitted in theconnection signaling CALL—in particular the call number RUNO1 and theemail address EMAIL1—and stores the call number RUNO1 and the emailaddress EMAIL1 with mutual assignment in the caller log CALLLOG aftertransmission SPE to the second database PBXDB2. An entry of this type isshown in the caller log CALLLOG in FIG. 2, with the column values forthe columns DATE and NAME, and other caller log entries, only beingshown by dots.

In the further course of time the second subscriber can accept theincoming call signaled by the connection setup signaling. Alternativelythe first subscriber can terminate the incoming call, before the secondsubscriber has accepted the call. This distinction and furtherprocessing steps in the context of the call are of no further relevancewith regard to the invention and are therefore not explained in moredetail.

Transmission of the email address EMAIL1 in the context of theconnection TV can take place in a special embodiment of the invention ina signaling segment actually provided for a different purpose, forexample in the segment for transmitting a display name. It is possiblein particular here for the start and end of the email address EMAIL1 tobe marked in this signaling segment in such a manner that the emailaddress EMAIL1 is identified by the second telephone EG2 from themarking and extracted, without the data structure actually provided fortransmission in this segment being lost.

In a subsequent method step the second subscriber can initiate acallback to the first telephone EG1 by activating a callbackfunctionality at the second telephone EG2. Alternatively a user actionat the second telephone EG2 or at the second email client EM2 canprepare for an email transmission to the first email client EM1. Thelast-mentioned user action—for example pressing a button on the secondtelephone EG2 or activating a pushbutton or making a menu selection at auser interface at the second telephone EG2 or at the second email clientEM2—initiates the reading out AUS of the previously stored entryrelating to the call number RUNO1 and the email address EMAIL1 from thecall log CALLLOG, with the address transfer unit AE of the secondtelephone EG2 transmitting the previously stored email address EMAIL1assigned to the call number RUNO1 to the second email client EM2 by wayof the CTI link CTIK (message USB in FIG. 1).

The second email client EM2 then opens an empty email window to composean email, in which the determined email address EMAIL1 is input for theaddress field. After additional manual inputting of an email text as thedata to be transmitted, the second subscriber can send the email to thefirst subscriber. When the second email client EM2 identifies theinitiation of the email transmission, an email MAIL is then transmittedas an SMTP message to the first email client EM1 by way of the datanetwork IPNW. Addressing here takes place by way of the input emailaddress EMAIL1, which was originally transmitted in the connectionsignaling from the first telephone EG1 to the second telephone EG2. Theaddress—in this instance EMAIL1—is again added as a subscript to themessage—in this instance MAIL.

The second subscriber is able to transmit data to the first subscriberby way of an alternative communication path in the manner describedabove. This is particularly advantageous, if the second telephone EG2 orthe second exchange PBX2 does not have access to the assignment tableZUORD. This is the case in conventional communication systems, if, as inthe present exemplary embodiment, the first and second telephones EG1,EG2 are linked by way of a public or private telephone network, by wayof which proprietary access to the assignment table ZUORD stored in thefirst database PBXDB1 is not possible.

The caller log CALLLOG is advantageously stored in the second exchangePBX2 or in the second telephone EG2 as a caller log or address book.Alternatively the call log can also be stored in an email address bookof the second email client EM2. Further call-related data can also bestored in the caller log CALLLOG and this can then be insertedautomatically into the email, for example in the subject line or in theemail text, in addition to the email address. Transmission of an entryin the caller log CALLLOG to the email client EM2 can preferably beinitiated by activating an entry in the caller log CALLLOG by displayingand selecting this entry at the second telephone EG2. To facilitateselection, similarly transmitted name information NAME of the firsttelephone EG1 is preferably also stored in the caller log CALLLOG and insome instances this is transmitted anyway to the called terminal inknown signalings to show a display name to be displayed on a displayunit.

It should be noted that in conventional communication systems atelephone connection is frequently switched by way of one or moreexchanges. The direct transmission shown from the first telephone EG1 tothe second telephone EG2 should therefore only be seen as a simplifiedabstraction. Similarly in FIG. 1 means for the CTI link and for emailtransmission and email storage—such as the use of email mailboxes andemail servers for example—are not set out in more detail, as this is notdeemed to be significant for an understanding of the invention.

FIG. 2 shows an alternative embodiment of the invention, with variouscomponents and method steps being identical to the embodiment in FIG. 1and therefore not being described again. In contrast to FIG. 1 in FIG. 2there is a link between the first primary service communication facilityand the second primary service communication facility by way of an IPnetwork IPNW. The first secondary service communication facility and thefirst primary service communication facility and the second secondaryservice communication facility and the second primary servicecommunication facility are applications on a workplace computer. Thefirst workplace computer PC1 here comprises in particular a telephoneclient TC1—generally configured as a so-called soft client—as a firstprimary service communication facility and a third email client EMS as afirst secondary service communication facility. The second subscriber isassigned a second workplace computer PC2, which comprises a secondtelephone client TC2 and a fourth email client EM4. Server facilities,which are required for a telephony application such as the telephoneclients TC1 and TC2, are not shown in FIG. 2 for simplificationpurposes. The only server component shown is the LDAP database (LDAP:Lightweight Directory Access Protocol), which is located like the firstworkplace computer PC1 in a local network of the first subscriber. TheLDAP database LDAP here holds the assignment table ZUORD known from FIG.1, which is written and updated by means of a communication servicepresent in the local network (not shown). The LDAP database LDAP inparticular stores generally unmodifiable communication data—such as callnumbers, email addresses, mail addresses—of many or all the subscribersin a company, department and/or organization. In particular a callnumber/email address value pair RUNO1-EMAIL1 is stored in the assignmenttable ZUORD, together with further entries shown by dots.

The second telephone client TC2 of the second workplace computer PC2 islinked to a call log database RDB, which comprises the caller logCALLLOG known from FIG. 1 and which, like the second telephone clientTC2, is an integral component of the second workplace computer PC2. Atthe start of the method the caller log CALLLOG is empty or containsentries which are not significant for clarification of the method andare only shown by dots in FIG. 2.

The sequence of the invention is now the same as FIG. 1. Activated bythe initiation of a connection and the dialing of the destination callnumber RUNO2 of the second telephone client TC2 at the first telephoneclient TC1, an interrogation message AM is sent to the LDAP databaseLDAP, in order to determine an email address EMAIL1 assigned to the callnumber RUNO1 of the first telephone client TC1. The telephone client TC1then uses this determined email address EMAIL1 to set up a call setupsignaling CALL to the second telephone client TC2 by way of thesignaling path SIGPF, with in particular the call number RUNO1 of thecalling telephone client TC1 and the assigned email address EMAIL1determined from the LDAP database LDAP being transmitted. The secondtelephone client TC2 then stores the transmitted address data RUNO1 andEMAIL 1 in the caller log CALLLOG of the call log database RDB. Theaddress data RUNO1 and EMAIL1 is hereby transferred, in some instancestogether with further data, by means of the message traffic SPEL to thecall log database RDB. The state of the caller log CALLLOG thencorresponds to the state shown in FIG. 2 with a common data set for thecall number RUNO1 and the email address EMAIL1—as well as further valuesonly shown by dots for further data set fields and further data sets.

Some time after a user action at the second workplace computer PC2 caninitiate the opening and displaying of an email text message at thefourth email client EM4, with the previously stored email address EMAIL1being read out by interrogation ABSA from the call log CALLLOG and beingtransmitted to the fourth email client EM4 to fill in a destinationaddress field of the email text message by means of an interprocessmessage INM of the second workplace computer PC2. The email text messageis now available to the second subscriber for further processing at thefourth email client EM4. A user action at the fourth email client EM4allows the email with the email address already filled in to betransmitted at a later time to the email address EMAIL1 inserted. In thepresent exemplary embodiment the user action causes the email textmessage to be transmitted to the first workplace computer PC1 and inparticular to the third email client EM3 by means of a message MAIL byaddressing to the destination email address EMAIL1. The first subscriberthus receives information from the originally called second subscriberin an alternative representation—text instead of voice—by way of analternative transmission protocol—an email protocol such as SMTP insteadof a voice protocol.

The method shown in FIG. 2 is particularly advantageous if the secondworkplace computer PC2 cannot access the LDAP database LDAP due to thenetwork structure. This is the case particularly when the LDAP databaseLDAP is configured in a non-public address space (and therefore thesecond workplace computer PC2 cannot address the LDAP database LDAP) oris protected by a firewall against access from outside a local network.A link between the respective telephone client and email client of aworkplace computer is preferably effected by way of interprocesscommunication. As an alternative or in addition to email transmission aninstant messaging method can also be deployed as the secondarycommunication service.

As well as the arrangements illustrated in FIGS. 1 and 2, the inventioncam also be deployed without restriction in further more complex systemarrangements. For example a line-oriented ISDN telephone can beavailable to the sending subscriber as a first primary servicecommunication facility and a WLAN-interfaced (WLAN: Wireless Local AreaNetwork) PDA (Personal Digital Assistant) as a first secondary servicecommunication facility, while an IP-based telephone is assigned to thesecond subscriber as a second primary service communication facility anda workplace computer connected to the internet by way of a LAN cable(LAN: Local Area Network) as a second secondary service communicationfacility. In an arrangement of this type provision should be made inparticular for a transition between an ISDN-based and an IP-basedtelephone network and a transition from a line-based to a radio-baseddata network.

Depending on the implementation of the transmission of the secondaryaddress information from the first primary service communicationfacility to the second primary service communication facility—forexample by extending an existing signaling protocol or by other use ofexisting protocol elements, for which there is generally noprovision—provision should possibly be made for simple protocoladjustments or conversions in the components in a signaling path forconnection signaling, such as gateways, gatekeepers and/or exchanges forexample.

In the figures the primary and secondary service communicationfacilities are terminals. However there is no restriction to terminals,as the method can also be deployed without modification on serverfacilities. For example automatic email messaging can be provided, beinginitiated by a server component as a second primary or secondary servicecommunication facility based on the incoming connection signaling.

The invention can also be extended so that an email can be generatedautomatically with a situation-based email text, possibly influenced bypredetermined rules. This can be used for example to notify the firstsubscriber automatically after expiry of a predetermined time period,that the second subscriber has not yet interrogated the call log or avoice message that may have been included during the time period andtherefore has also not yet carried out any actions that may have beenrequired by the first subscriber.

Also information about the previous connection signaling—for example thetime when the connection signaling took place, whether the connectionwas not answered, or the connection was rejected due to a busy state,whether a message was left on the answering machine—can advantageouslybe included in the useful text for the transmission of data to the firstsubscriber by email or instant messaging message. This allows a semanticreference to be established to the previous connection attempt.
